Lighting Device With Magnetic Attraction System for Orienting the Light Beam

Abstract

A lighting device which comprises a box-shaped body and a light source in the body, with at least one wall that allows passage of a light beam generated by the light source. The box-shaped body includes a pivotable support mounting the light source such that it is rotatable about at least one axis of rotation for adjusting the angle of the light beam generated thereby. The device also has a magnetic attraction member for controlling the axis from the outside the body.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to the field of lighting appliances and particularly to a lighting device, especially but not exclusively of the type intended for flush mounting in floors, in which the light beam is orientable.BACKGROUND ART[0002]In certain situations it may be necessary for the direction of the light beam produced by a lighting appliance to be adjustable according to need. For such purposes, there are known devices wherein the orientation of the light beam is obtained by rotating the entire lamp body, which is pivotally connected to its base. Since a solution of this type is not always acceptable or feasible, alternative lighting devices have been proposed wherein the assembly of the body is fixed while the light source is installed on a support which allows for it to rotate. However, the rotation of the support to change the orientation of the light beam may pose some problems.[0003]In fact, adjusting the inclination of the ligh...

AI Technical Summary

Benefits of technology

"The present invention is a lighting device that allows for adjustment of the orientation of a light beam through a pivotable lamp base. The device contains a box-shaped body and a light source housed inside. The body has at least one wall through which the light beam is emitted. The device also includes means for exerting an attractive magnetic force to enable the base to be rotated around an axis of rotation from the outside of the box. The cursor is connected to the base so that the displacement of the cursor and the rotation of the base are cinematically linked. The device also includes reversible locking means to secure the position of the cursor. The technical effect of this invention is that it allows for easy adjustment of the light beam orientation through a pivotable lamp base, which is controlled by means of an attractive magnetic force."

Problems solved by technology

Since a solution of this type is not always acceptable or feasible, alternative lighting devices have been proposed wherein the assembly of the body is fixed while the light source is installed on a support which allows for it to rotate.

However, the rotation of the support to change the orientation of the light beam may pose some problems.

Dismantling the glass cover protecting the lamp may prove particularly laborious, especially in the case of flush-mounted, watertight lighting appliances of the type often needed for installation in outside environments, e.g. along paths leading to the door of a home, or in interiors with a high degree of humidity, such as kitchens or bathrooms.

The watertight feature of the appliance may also be lost due to wear on the sealing gaskets deriving from repeated dismantling, or due to an erroneous re-assembly of said sealing gaskets.

On the other hand, the provision for a mechanical transmission of the beam-adjusting action accessible from outside the device to avoid the need for said dismantling procedure would not only be functionally and aesthetically unacceptable, but would also be unsuitable for use in watertight flush-mounted appliances because of the consequent risk of infiltration around the area of the operating element of transmission.
